NAILING APPARATUS.

SPECIFICATION forming part Of Letters Patent'No. 695,385, datedMarch 11,1902.

Application filed December 17, 1900. Serial No. 40,080. (No model.)

drawings, is a specification, like characters on the drawingsrepresenting like parts.

In another application, Serial No. 3%,877, filed October 30, 1900, Ihave shown and described a nailing apparatus having a hopper which maybe rotatedwhile thedriver is inoperative to load the raceway with tacks.

The invention to be herein described is intended to be an improvementon' theappa ratus shown in said application.

One feature of invention herein contained is a provision for stopping orstarting the shaft carrying the pinion employed to rotate the hopper, Iusing, as herein shown for such purpose,.a clutch. I have also produceda novel pick-0E and stop, it presenting double points to better controltliem'ailor tack. I have also devised a novel clearer'to dislodge anynails or tacks improperly deposited upon the raceway.

Figure 1,in side elevation, represents a nailing-machine hung up in itsinoperative position that its raceway may be filled. Fig. 2 is a viewlooking at the hanger and'its driving mechanism from the left, Fig. 1.Fig. 3 isa section through the apparatus, raceway, and

hopper. Fig. 3 is a detail of the upper end of the raceway. Fig.4. is adetail showing the pick-off, nose, and driver in one of its positions.Figs. 5 and 6 show the pick-0E from its side nearest the end of theraceway and the nose, the pick-0E being in different positions. Fig.'Zshows the pick-off in perspective; and Fig.8 is a section in the linea, Fig. 3.

The frame or hand pieceA presentsa tube having an extension A, which maybe provided, as shown, with a stud A, which may enter notchesof abracket or wall piece 13, adapted to be secured to any suitable support,as a wall, by a screw. The extension also serves to sustain the hracewayC and hopper G, to be described. The tubular part of the frame containsa bearing a for adriverbar a havin' a driver a said driving-bar havingat its upper end a shouldered head a provided with a depeiiding tube (1.which, as shown, enters 'the tub ular part of the frame. A spring aresting at one end on the hearing a and acting at itsother end againstthe head, keeps th e'driver bar normally in its inoperative position;The extent of movement of the bar a by the spring a is controlled by astop a which enters a slot a in the bar. The driver-bar hasat its lowerend a finger a which at each descent of said bar meetsa roller or otherstud e of a slide E, a suitable spring,v as 9', moving the said slide inthe 0pposite direction.

The nose D, inserted in the lowervend of the tube A, is groovedtransversely to sustain and guide the substantially U-shaped slide E inits movements, and said nose is also notchedto' sustain the'llo'wer endof the raceway G, as shown in Fig. 3. The lower end of the racewayenters the open. space e between the arms of the slide, and the grooveof the said rac'eway,in which hang the bodies of the nails, is in linewith a slot in the side of the nose, that nails may enter thenail-passage d in said nose.- InOrder that the nails may enter the nosesingly who acted upon by the driver, eacharm of the slide is providedwith two prongs, the said prongs constituting two pairs ofoppositelydisposed prongs ,facing each other, each arm of tge T e saidprongs are separated to leave a diagonal space between the contiguousends of each pair through which each nail taken from the end of theraceway by said prongs passes on its :way into the driver-passage; Bythe employment of the lower pair of prongs e e it becomes possible tocontrol and'position .the point 'or lower end of the nail, whatever itslength, and prevent 'it from tipping on the upper side of the prongs 6 esothat the point of said nail will meet the nose in the bottom of theslot therein through which the nail enters the nose. The nose has avertical slot d in which is pivoted a nail-supporting device d actedupon by a spring dfiwhich normally keeps the hooked lower end of saiddevice in position to arrest each nail picked off the raceway by theslide E until said nail I is struck by the driver. The raceway, composedof a bar having a suitable slot or groove, is held in place by suitablescrews 0, other screws a holding in place the cover c in usual manner.The upper end of the raceway entering the hopper G has a wing c, onwhich the nails lifted by the shelves g of the hopper drop, the pointsof the nails entering the groove of the raceway, while the heads of thenails are sustained thereby. The inner end of the hopper has a flange g,which enters a circular groove between a ring 9 and a circular plate gpreferably forming a part of the frame'casting. The inner or left-handside (see Fig. 3) of said ring and casting has also, as shown, acircular guideway or groove, which, as shown, receives a series ofcarriageblocks 9 connected with said hopper by suitable screws g saidcarriage-blocks and the end of said hopper traveling in said circulargrooves as the hopper is rotated. By supporting the foot of the hopperat one end in a circular groove I obviate the employment of a shaftextended centrally through the hopper, and the space inside the hopperis less obstructed, enabling the diameter of the hopper to be reduced.The hopper has connected with it by suitable screws a toothed ring 9 Theright-hand end of the hopper is provided with a door g sustained bysuitable hinges g. The casting g has pivoted to it at h a clearer h,shown as a spring'controlled lever having its upper end inclined (seeFig. 8) to be struck by a series of rollers or other studs on, carriedby screws m, inserted in the flange g, the lower curved end of saidclearer eX- tending transversely to the raceway and being vibratedopposite the stress of the spring 2 and occupying always a positionabove the racewayjust above the upper end of the cover, the cleareracting as a gage to enable the heads of nails properly seated in saidraceway to descend and by its curved lower end removing from the racewayany nails or tacks lodged thereon improperly.

To prevent a nail lodged crosswise on the raceway from entering thespace between the under side of the clearer, occupying always a positionover the raceway, and the top of the raceway, I have erected on the sideof the race way a stop 10, (see Fig. 3, full lines, and Fig. 3, dottedlines,) the upper end of said stop extending above said raceway andarresting such nails.

The clearer, in order that it may operate properly and not be subjectedto lateral strain to thereby bind the clearer on or strain the pivot h,is guided at its lower end by means of a stud m the shank of which isextended through a slot in the plate g and enters the clearer, the headof the stud moving close to the said plate. By extending the head of theclearer through the slot in the plate 9 the said clearer may be manuallyvibrated by means of the stud 012 should the said clearer stick or getcaught.

hen the operator commences to use the apparatus, he holding it in onehand, the raceway is supposed to be filled up with nails or tacks, andwhile the apparatus is used in driving nails the hopper is usually atrest.

\Vhen the apparatus is not being used, as when, for instance, a workmanis preparing a shoe to receive nails or tacks for lasting or for otherpurpose, the workman hangs the frame upon the bracket B, as in Fig. 1,so that the toothed ring g is put in mesh with the pinion H on a shaftH, having its hearing in said bracketand provided at its opposite endwith a bevel-gear H which is engaged and driven by a bevel-gear H on amain shaft H provided, as herein shown, with a belt-wheel J, loosethereon, and provided with a stud 3, forming part of a clutch, the otherpart being a stud 4, carried by a block J, having a pin 5, enteringloosely a slot 6 in the shaft H By the employment of this clutch it ispossible when in the position Fig. 2, the clutch being separated, toenable the pulley J to be run, it being driven by a belt (not shown)actuated by a pulley from any usual connter-shaft without rotating theshaft 11 and the hopper. When it is desired to rotate the hopper to fillthe raceway, the clutch will. be made operative by sliding the hub Jtoward the hub of the pulley, and whenever the raceway has been filledthe clutch will be opened and the further rotation of the hopper bestopped.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, 1's
